Ok I got the background reflection on my 3D models Buildings on the widows , actually was very simple to do thanks for the Tutorial.

what I am having real problem with the 3D models buildings that I zoom in or out , if it is real time or rendered ,full resolution or low , or if zooming from far or closer the problem is the same , causing I think call it shimmering /Ramping antennas , kind of shiny and flickering when i zoom in or out, and i am using I Mac and hit film 2 and I tried on HF4 pro the Demo.

@jaa - Triem23 had mentioned above the that HF4 has a new render engine that helps reduces z-fighting. I have a IMac as you do and I had a lot of shimmer problems with HF3 but after the update in 4 the problem seem to go away. Now and then I do get aliasing problems, either due to bad geometry with the model or at times my Mac itself.

The max my Mac can export when it comes to anti-aliasing is 8xMSAA which is due to my GPU. Sadly the PC out does the Mac when it comes to GPU performance. Many PC's , with the right video card, can produce 32xMSAA

Hi Axel do you have any answer for me regard to my comment above? because the problem with 3D models that I zoom in or out something to do with anti-aliasing ,if I can find out where I can increase anti-aliasing , because on the project screen i can't find any AA as you said.

Your silly question that you mentioned above ( viewing/render in Full , half or quarter resolution? ) Thanks for the tip , I always had it in Full resolution ,then I switch to Anti-Aliased now is much better looking than before, still I am getting a little shimmer problems but i can't do anything about it because I am using HF2U ,according to Triem23 you can not customize Anti-Alias settings with HF2U, I have two wait for HitFilm 5 pro to upgrade ,hopefully comes soon. Thanks for all the HELP.
